nexj.core.meta.persistence.sql.RelationalPrimitiveMapping
Relational mapping of an attribute containing a primitive value.

         Object obj = instance.getValueDirect(m_variablesAttribute.getOrdinal());


         if (!(obj instanceof Undefined))
         {
            RelationalMapping mapping = (RelationalMapping)instance.getPersistenceMapping();
            RelationalPrimitiveMapping attrMapping = (RelationalPrimitiveMapping)mapping
               .getAttributeMapping(m_serializedVariablesAttribute);


            SQLWork work = (SQLWork)adapter.addPrimitiveWork(uow, instance,
               adapter.findWork(uow, instance, mapping.getPrimaryTable()),
               attrMapping, (obj == null) ? null : "");


            if (work != null)
            {
               work.setValue(attrMapping.getColumn(), null);
